Hello Laurent

We have API Routes for the Amelia app, but most of them are protected depends on of the permissions that is set in WordPress Accounts. You can check those API Routes in this file ../wp-content/plugins/ameliabooking/src/Infrastructure/Routes/Routes.php

At the moment we have some JavaScript hooks that are triggered depending on the view:

window.beforeAddToCalendarLoaded()
window.beforeBookingLoaded()
window.beforeSearchLoaded()
window.beforeSearchFiltered()
window.afterSearchFiltered()
window.beforeConfirmedBooking()
window.beforeCatalogLoaded()
window.afterSelectCatalogCategory(object_category)
window.beforeCatalogCategoryLoaded(object_category)
window.beforeCatalogServiceLoaded(object_category, object_service)
window.afterSearchActivateService(object_appointment, object_serviceActive)
window.afterSearchGoToSecondStep(object_appointment, object_serviceActive)
window.afterBookingSelectDateAndTime(object_appointment, object_serviceId, object_providerId, object_locationId)
window.afterBookingSelectService(object_appointment, object_serviceId, object_providerId, object_locationId)
window.beforeConfirmBookingLoaded(object_appointment, object_service, object_provider, object_location)
window.afterConfirmBooking(object_appointment, object_service, object_provider, object_location)

JS files are modified (minimized) in public version of plugin (in our development environment is accessible), but unfortunately I can not send you our source code because that is the policy of our company.

All those files that have extension .vue are compressed and minimized in JS files that is very hard and not recommended modifying. So in order to add some other features you can unminify the js and customize it.
